Scientists Link CO2 and Fossil Fuel Emissions

Human caused Global Warming proof published.

Scientists confirm by direct observation Carbon Dioxide’s Green House Effect with 11 years study conducted in both Alaska and Oklahoma. The scientists were able to link rising CO2 levels with human activity-primarily the burning of fossil fuels. By using archival records similar to those provided by Resolute AI, the scientists could directly compare CO2 levels over the course of the past century. This revealed a clear upward trend, as can be seen in the graph below. The observed measurements confirm theoretical model predictions of the greenhouse effect due to human activity.

CO2 and fossil fuel link

Scientific smoking gun type proof that burning fossil fuels cause increase greenhouse effect & global warming

The results of the study were published online in Nature (Science Journal) Feb 25th, 2015. The paper “Observational Determination of Surface Radiative Forcing by CO2 from 2000 to 2010,” was released by scientists from Lawrence Berkeley National Laboratory; University of California, Berkeley; University of Wisconsin-Madison; Atmospheric and Environmental Research Inc.; and Pacific Northwest National Laboratory. Authors of the paper (D. R. Feldman, Bill Collins, Jonathan Gero, Margaret S. Torn, Eli Mlawer & Timothy Shippert provided the evidence. The 11 years of data was primarily sourced from the U.S. Department of Energy’s Atmospheric Radiation Measurement Climate Research Facility, known as ARM.

The data from 3300 measurements from Alaska and 8300 measurements from Oklahoma confirms that rising carbon dioxide levels can be traced to human-caused fossil fuel emissions and helps confirm that climate models are accurately representing carbon dioxide’s impacts to climate.

CO2 measurements were made using Atmospheric Emitted Radiance Interferometer equipment that compared atmospheric CO2 concentrations with surface radiative forcing due to C02 at two different locations (North Slope of Alaska and Oklahoma). The measurements confirm that the Earth absorbed more energy from solar radiation than was emitted as heat back to space. Interferometer technology, which was used to gather these readings and measurements, often utilize hardware such as that from Edmund Optics, like the helium-neon laser.

The lead Author of the Nature paper Daniel Feldman, a scientist in Berkeley Lab’s Earth Sciences Division says “Numerous studies show rising atmospheric CO2 concentrations, but our study provides the critical link between those concentrations and the addition of energy to the system, or the greenhouse effect”.

The instruments were able to isolate the contribution of CO2 from other factors such as clouds, water vapor and seasonal changes caused by the influence of photosynthesis.

The scientists were able to link increasing CO2 from 2000 to 2010 with attributed radiative forcing to fossil fuel emissions and fires. Said another way this 11 years of in the field measurements and data provides scientific proof that CO2 released from fossil fuels does cause an increase in greenhouse effect and thus global warming.
